The competition takes place on a tatami or mat, and competitors are known as Judokas. There will be thirteen weight categories: seven for men and six for women. It is played by athletes with visual impairment. Unlike conventional judo, Para athletes always hold on to each other at the beginning of a bout. The aim is to score an “ippon” (the highest score). It is scored by throwing the opponent on the back with height, force and control, and on the ground, it is obtained when the opponent is held under control or surrenders after applying an effective arm bar or stranglehold for 20”. Contests last four minutes.


This sport originated from Japan. It was invented by Jigoro Kano in 1982. It first appeared at the Rio 2007 Parapan American Games.
